How does the compression work?

Image compression works like a smart space-saving tool for your photos and graphics. When you compress an image, special algorithms analyze the file and remove unnecessary data while trying to maintain visual quality. This process significantly reduces file sizes, helping your website load faster and use less storage space. Different image formats (JPG, PNG, AVIF, WebP) use various compression techniques: JPG compression focuses on reducing color information thats less noticeable to the human eye. It works particularly well for photographs and complex images with many colors and gradients. PNG uses lossless compression by default, which means it maintains perfect image quality while reducing file size by efficiently organizing the data. Its ideal for graphics with text, logos, and images that need crisp edges. AVIF and WebP are modern formats that offer superior compression while maintaining excellent visual quality. They combine the best aspects of both JPG and PNG compression methods, making them highly efficient for web use. Quality settings between 1% and 100% give you control over the compression level: - 100% quality means minimal compression with maximum visual quality - 50-80% often provides a good balance between file size and appearance - Below 50%, youll start noticing visible artifacts like blurriness or color banding - Very low quality (1-20%) results in significant visual degradation but tiny file sizes Framebird automatically applies optimal compression settings for each format, ensuring the best balance between quality and file size. However, you can adjust these settings based on your specific needs: - Higher quality for professional photography or detailed product images - Medium quality for general website images and blog posts - Lower quality for thumbnail previews or background images Remember that faster-loading images improve user experience, boost SEO rankings, and reduce bounce rates on your website. Even a small reduction in file size can make a significant difference when multiplied across many images.
